The Ambassador features the Ultra Pocket Spring System. The Ultra pocket 5 zone system with soft shoulder and integral back support uses 40% more springs than the Royal. Each spring is heat treated so that it has a memory and individually wrapped in its own pocket. This provides luxurious support for the whole body so that you sleep well and become invigorated for the next exciting day. The mattress springs are encased in Talalay Latex, a natural filling, which has excellent ventilation properties, for the regulation of heat and moisture. The latex provides a luxuriously soft surface for you to lie on, which works in harmony with the zoned springs. To allow the spring unit to work effectively, a special stretch jersey fabric is used on the sleeping surface allowing it to shape to your body and provide total support. To make life easier, there is no need to turn the mattress and you can select different tensions for your individual needs. The Ambassador is available in all standard and special sizes on request and as a Continental and an Aqtive Adjustable. Tensions available: (Medium, Firm) Upholstered in Microfibre and available in a choice of Oatmeal or Chocolate.
